An official who spoke to the Associated Press only on the condition of anonymity, said investigators have asked the famous Mexican star to meet with them about her ties to Guzman and the get-together she arranged earlier this year with the planet's most-wanted kingpin.

Guzman was captured in a bloody shootout on Jan. 8 after Mexican marines raided his mountain-top hideout, led there in part because of Guzman's meeting with the celebrities and communications he had with them about a movie he was peddling of his notorious life.

Penn said on "60 Minutes" that he has regrets about the interview he conducted with Guzman, which was published by Rolling Stone magazine.
